First Look: Yantouch Black Diamond 2 3D Dock

Yantouch's new Black Diamond 2 ($59, aka BD2) is a sequel to the unusual light-reflecting gem-like plastic iPhone dock we reviewed earlier this year. Virtually identical from the outside with some new electronics hidden inside near the dock, Black Diamond 2 is now capable of illuminating itself without an iPhone inside, generating red, blue, green, yellow, and orange colors in a slow flow mode. It can also now enhance a docked iPhone's sound by 2.5 times using a passive amplifier, improving upon the prior version's speakerphone performance as a consequence. As before, the unit comes with a USB cable for charging and syncing your iPhone, which now also supplies power for the internal lights as well.

Editors' Note: iLounge only reviews products in "final" form, but many companies now change their offerings - sometimes several times - after our reviews have been published.
This iLounge article provides more information on this practice, known as revving.
